The versions of malware called Ransomware are among the most dangerous online threats, known to us at the present moment. The specific version we are elaborating on in the paragraphs below – Jaff Decryptor System Ransomware, doesn’t make an exception. It is harmful and causes unpleasant encryption of some of your files, reaching ever further in disturbing you by later asking for a ransom to be paid for them as well. Ransomware is not one single type. The most general idea of Ransomware is actually the file-encrypting type, just fitting the description above. Throughout the years, smaller groups defined as Ransomware but with slightly different functions appeared. For instance, some Ransomware gets used by the state agencies to fine/punish some cyber criminals. Other types are just exploited for locking your monitor and asking for money to unlock it. There could also be mobile Ransomware-based viruses, which will make your smartphone inaccessible and you will need to pay to access it.

Basic details about the file-encrypting Ransomware

Ransomware, as you have already read above, is a type of malicious software that is exploited for blocking data and making it inaccessible and then – demanding an amount of money to be paid in return for this data’s recovery. Such software is awfully hard to counteract. Even if the demanded ransom is fully paid, you can never be certain that the affected users will ever get their locked-up files back. Whatever the affected users do to delete the virus will NOT return their data as well – the malware might by removed, bu that won’t necessarily remove the encryption from the files. 

Ways of functioning of viruses like Jaff Decryptor System Ransomware:

Jaff Decryptor System Ransomware could infect your PC in many various ways. For example, sometimes Trojans are used for the purpose of detecting vulnerabilities in the operating system, or another additionally installed program on your computer, and help another virus get in. After having found such a weakness, the virus can use it to sneak a Ransomware version in. One more probable distribution tool is the infamous practice of malvertising. Actually, this is the process of generating fake pop-ups, which lead to locations full of malware or contain malicious scripts of viruses themselves. In this case, once you click on the suspicious ad, this malware gets injected into your PC. Ransomware may also come from contagious websites that you find browsing the web; malicious torrents; or infected emails. No matter how it has gotten to you, Jaff Decryptor System Ransomware typically functions in the following way:

Everything begins with the assembly of a list of all the files that you regularly use and/or open. This list is the guideline for the encryption process – it shows the virus the locations and the names of the files. Detecting all such files could be a process consuming much CPU and much RAM because a full scan of your disks is completed. The real encrypting starts and all the data from the list gets locked-up. This process may also call on a lot of your system resources. In some very rare cases, some affected users might see a strange process taking place in their Task Manager. Such a possibility is quite favorable because you will be able to terminate the infection while it is still taking place. What is recommended is that you disconnect your computer from all the networks it participates in and to turn it off immediately. Then you should search for some professional help. Such a case is very unlikely to happen, though. Most of the infections will go unnoticed and finish with the generation of a harassing message on your desktop, which will inform you about the demanded ransom, and warn you about the future of your blocked files.

What is the best solution after all?

So far no tool or strategy can promise you the full recovery of your files. We cannot tell you exactly what you should do in your case, but we can explain the possible solutions here and you can decide for yourself.

  1. You may pay the ransom. Just bear in mind that this is not very clever because it doesn’t make the hackers decrypt your data, it may just motivate them to encrypt somebody else’s files. In our honest opinion, you should not hurry to do that. No guarantees of recovering your files are given.
  2. Perhaps you want to try fighting the virus on your own. For instance, via using a special Removal Guide. Simply scroll till the end of this article and follow the instructions there. We want to remind you again that we are not making any promises about the removal of Jaff Decryptor System Ransomware, or the restoration of your encrypted data.
  3. Go and see someone who has experience dealing with such malware. Who knows, such people may have special tricks and may solve your problem.
